Nanhauang-His stream and The Beihaung-His are located in the volcano function area, the stream has introduction of the sulphur gas and hot spring water of volcano, changes the environmental condition of the water body, influences the heavy metal and moves the course.There is a hot spring in area on the volcano after one The Shuang-His streams belongs to too, but the carbonic acid spring, there is less content of sulphate.Therefore, we can realize it was pH value that influenced the dissolving heavy metal to move mainly.

南磺溪与北磺溪的地区属后火山区域有喷气孔、硫气孔和温泉的存在,溪水有火山硫磺气体与温泉水的输入,改变水体的环境条件,影响到重金属迁移过程,双溪也属后火山区域有一处温泉,但属於碳酸泉,硫酸盐含量较少,由此我们可知,主要影响溶解性重金属迁移的是pH值。

Study it is tall purity, OK to fight eroded vitreous kiln to use actor * qualitative silica brick so the service life that prolongs vitreous kiln on certain level. 1 experiment develops vitreous kiln to be handpick and high grade raw material with the main avenue of high grade silica brick, the purity; that the alkalescent oxide content that in reducing raw material, takes will come to raise silica brick deserves to compare through adjusting raw material grain, apparent pore is reduced to lead when shaping in order to raise compact sex, achieve fight erode the effect.

所以探究高纯度、抗侵蚀的玻璃窑用优*质硅砖就可以在一定程度上延长玻璃窑的使用寿命。1试验研制玻璃窑用优质硅砖的主要途径为精选优质原料,降低原料中带入的碱性氧化物含量来提高硅砖的纯度;通过调整原料颗粒配比,成型时降低显气孔率以提高致密性,达到抗侵蚀效果。

灌水前拧开放气螺塞,然后加水,直到从放气孔向外冒水,再转动几下泵轴,如继续冒水,表明水已充满,然后关闭放气螺塞,准备起动。

In summary, various key experimental conditions in electron acoustic imaging of ferroelectric domains were systematically studied. The optimum experimental conditions to obtain EAI of domains with good quality and the factors important to image analysis have been presented. The piezoelectric vibrator model and calculation of motion equation are helpful for explaining the imaging mechanism and related experimental phenomena. The sample holder with variable electric field was designed. The domain movement of BaTiO〓 ceramics and crystal under lateral and longitudinal applied electric field and domain movement of PMN-PT crystal under longitudinal poling electric field were observed. The application of SEAM on revealing of ferroelastic domains, imaging of residual stress distribution in ceramics coatings and around the pores on the surface of ferroelectric ceramic composite have been reported respectively. All these works enriched the study of electron acoustic imaging and extended the application of SEAM in the characterization of materials.

综上所述,本文系统地研究了各项关键实验条件对电畴电声成像的影响,指出了获得最佳畴结构电声像的条件和成像分析中应当考虑的各种影响因素;提出了解释电畴电声成像的压电振子模型,在此基础上推导并求解了压电振子运动方程,并对一些实验现象作出了解释;成功地设计了可变电场的样品台,观察了BaTiO〓陶瓷和晶体在横向电场作用下的畴运动,PMN-PT晶体在纵向极化电场作用下的畴运动;探索了电声显微镜在铁弹畴成像,陶瓷涂层应力观察,陶瓷自然表面气孔周围应力成像的应用,这些研究,丰富了电声成像的学术内涵,拓展了电声显微镜的应用领域。

Also said driving, tried to play the version only to provide NESSION 350Z, but some four kind of different color different re-equipping edition chose (partner for you to think this vehicle buttocks oversized, kept off line of sight very much), had under the QUICKPLAY pattern around the city and drifts two kind of patterns: The around the city pattern is four Che Bishui arrives the end point most quickly, this racecourse is not very long, but has several S curves to need to be careful, the vehicles were inferior the previous generation easy to control, feel and NFS5 are similar, belong to the design quite real that kind, when immediately is turning around in particular front of a train if you hold down the acceleration key not to put the automobile to be able in-situ to spin, discharges the big group the smog, the air vent also can torch.

游戏的音频似乎没有特别值得关注的地方,大部分是赛车发出的声音,诸如发动机的轰鸣声和刹车时轮胎摩擦地面发出的声音等,音乐和环境噪声相当的低,有3首歌供选择,还是那种动感十足的 Hiphop 曲风。再说说驾驶,试玩版只提供了一辆 NESSION 350Z ,不过有四种不同颜色不同改装的版本供你选择(偶认为此车屁股过大,很挡视线),在 QUICKPLAY 模式下有环城和漂移两种模式:环城模式还是四辆车比谁最快到达终点,该赛道不是很长,但有几个 S 弯道需要小心,车辆不如上一代易控制,手感和 NFS5差不多,属于设计比较真实的那种,尤其是在马上掉转车头的时如果你按住加速键不放汽车会原地打转,排出大团的烟雾,排气孔还会喷火。
